which are feebly obliquely truncate internally, with the exterior 

 angles obtuse, but not produced; surface regularly convex, rather 

 even, and each elytron with an oblique longitudinal costa on disk 

 extending from behind the humerus to apical third, rather densely 

 and irregularly jjunctate, the punctures coarser on basal region but 

 becoming more obsolete toward the apex, densely clothed with 

 recumbent brownish-white pubescence, which is browner toward 

 the sides behind the humeri, broadly cinerous along the base, the 

 brownish-black markings narrowly bordered anteriorly with cine- 

 reous pubescence, with a few small, irregularly placed black spots in 

 basal region, along suture and anterior margins, and on the discal 

 costae, and each elytron ornamented with brownish-black markings 

 as follows : Two small spots along the lateral margin, one at humeral 

 angle, the other behind the humerus, and a bisinuate oblique fascia 

 behind the middle, posterior to which are two irregularly shaped 

 spots, which are more or less connected to the fascia anteriorly. 



Beneath finely, densely punctate, and rather sparsely clothed with 

 cinereous pubescence; last abdominal segment strongly narrowed at 

 apex and produced slightly behind the elytra ; tibiae more or less 

 annulated with brown; tarsi and tarsal claws brownish-black; pro- 

 sternal process as wide as coxal cavity; femora strongly clavate at 

 apex. 

 Length, 9.5 mm. ; width, 4.2 mm. 

 Tyye locality. — Nagua, Oriente, Cuba. 

 Type.— C^t. No. 28398, U.S.N.M. 



Described from a unique female collected at the type locality 

 July T, 1922, by S. C. Bruner and C. H. Ballou. 



In this species the female has a very short extended ovipositor 

 as in Atrypaninus, but can be easily distinguished from the species 

 in that genus by the lower lobes of the eyes being rounded and 

 not longer than wide. It is not entirely congeneric with Leptosfyhis, 

 on account of the short extended ovipositor, but seems to be inter- 

 mediate between Atrypanius and Leptostylus; however, it seems 

 advisable to retain it in the latter genus, at least for the present, 

 until more material is available for study. 



LEPTOSTYLUS PYGMAEUS, new species 



Form very small, short, robust, and strongly convex, dark brown, 

 rather densely clothed with yellowish pubescence, and ornamented 

 with dark brown and cinereous pubescent markings; mandibles 

 brownish-black; palpi yellowish-brown. 



Head about as long as wide, nearly flat, and slightly narrowed 

 above in front, broadly and rather deeply concave between the 

 antennal tubercles, which are moderately developed and rather 

 widely separated, the surface subopaque, densely, finely granulose.
